Hi everyone. Glad to join the forums. I have a 1.42GHZ mini and a 20.1 inch Formac 2010 Gallery DVI display (1600x1200) I'm getting horizonal streaking over dark areas of the screen or anything with motion including games and DVDs. I know that I am not the only one with this problem. I just want to know what everyone else has suggested to fix this dilema.

I don't have the problem. I read that using SwitchRes X and switching to a lower resolution or helps. Have you tried another display?

yes it works fine with a couple of VGA displays. but im dumbfounded that a 3rd party apple company has monitors that the mini will not run correctly. So i'm going to try this switchres X ASAP and see if it works.

Would installing SwitchRes X and changing the hertz fix the issue. Since it's an obvious software problem that apple isn't dealing with.

I just installed SwitchRes X and created an array of refresh rates at 1280x1024. I don't have the issue at resolutions lower than that. The problem dropped dramatically at 58Hz and disappeared completely at 57Hz.

So SwitchRes can work, at least for some monitors. However, I'm a little annoyed that we have to resort to buying a 3rd party utility to fix this.
